Low-dose Perioperative Dexamethasone Improves 24-hour Post-Operative Pain after Anterior Cruciate Ligament Reconstruction

@#Introduction: Post-operative pain following anterior cruciate ligament reconstruction remains an important challenge. Steroids are used in various surgical procedures to decrease post-operative nausea, vomiting and pain. However, only a few studies have reported the effect of systemic administration of steroids in controlling postoperative pain after anterior cruciate ligament surgery. Materials and methods: We have conducted a prospective randomised trial with 109 patients divided into two groups to determine if administration of dexamethasone in the perioperative period improves pain in the post-operative period. The patients were divided into two groups: D, treatment (dexamethasone) and P, control placebo (saline). Patients in the D treatment group were given the first dose of 10mg of intravenous dexamethasone intravenously intraoperatively and the second dose on transferring of the patient to the inpatient department. The patients in the placebo P group, were administered normal saline in the perioperative period in a similar manner. Result: Post-operative pain was significantly less in the dexamethasone group at rest and on walking (p<0.001) for the first 24 hours after surgical procedure. Subsequently, the VAS pain scores were almost similar in both groups at 48 and 72 hours. The administration of dexamethasone resulted in less requirement of antiemetic and rescue analgesia medication There was no difference in range of motion and wound complications rate during the follow-up period at six months. No adverse side effect, like osteonecrosis of the hip, was detected. Conclusion: The pain following anterior cruciate ligament reconstruction is severe during the first 24 hours and perioperative administration of dexamethasone can decrease the post-operative pain substantially.

Jaundice in Plasmodium falciparum.

Thirty-two patients of smear positive Plasmodium falciparum malaria having jaundice were analysed retrospectively. Majority of the cases were in the age group of 31-40 years. Serum bilirubin levels ranged from 2 mg to 40 mg%. Fourteen (42.6%) had serum bilirubin above 10 mg%. Conjugated bilirubinaemia was found in twenty one patients (65.5%), unconjugated in 4 (12.5%) while 7 patients (21.8%) had a mixed pattern. Serum transaminases were high in 21.8% patients. Twenty five patients (78%) had associated azotaemia, 11(34.3%) had intravascular haemolysis and 3(9.3%) had possible cerebral malaria. Hepatosplenomegaly was seen in all the 32 patients. Mortality was 21% but none died of hepatic encephalopathy. Histologically the most consistent finding in liver biopsies was reticulo-endothelial cell hyperplasia. Pigmentation in kupffer cells, fatty change, sinusoidal and portal infiltration and cholestasis were the other features seen.
